Technical Field

Background
The optical fiber is a core component of a fiber laser light source, and the application of the optical fiber comprises the following components: transmission laser, amplification laser, frequency conversion of laser, and the like. Generally, passive optical fibers are used for transmitting laser, gain optical fibers are used for amplifying laser, and nonlinear optical fibers are used for frequency variation. The three types of optical fibers can generate heat due to laser loss in the working process. When the laser power is too high, the heat accumulation due to the laser loss becomes more severe, and the conventional natural heat dissipation cannot meet the requirement. At this time, the optical fiber may be fused or the loss of the optical fiber may be increased, which may affect the normal use of the optical fiber. In order to ensure the normal use of the optical fiber under high power, the optical fiber needs to be actively cooled.
With the rapid development of fiber laser technology, fiber laser light sources have been applied to various industries in society. The optical fiber heat dissipation technology is one of the core technologies in the optical fiber laser technology. The advanced optical fiber heat dissipation means is a key point for ensuring long-term stability and reliability of optical fiber laser products. The main method for dissipating heat of the optical fiber at present is an indirect heat conduction mode, and the specific method is as follows: firstly, etching an optical fiber groove on a metal plate, placing an optical fiber with high heat load in the optical fiber groove, and conducting heat to a metal substrate through the optical fiber groove; and then the metal substrate is cooled by air cooling or water cooling, so that the indirect heat dissipation of the optical fiber is realized. The method has many disadvantages, such as small contact surface between the optical fiber and the substrate, influence on heat dissipation effect, air gap between the optical fiber and the substrate, influence on heat conduction effect, indirect contact between the optical fiber and a cold source, large temperature gradient, and influence on the heat dissipation effect of the optical fiber. On the other hand, in order to dissipate heat of the optical fiber, the optical fiber must be attached and wound on the metal substrate, which severely constrains the optical fiber, resulting in that the optical fiber cannot leave the metal substrate, abandoning the length advantage of the optical fiber, and causing loss to a part of the optical fiber laser that needs to exert the length advantage of the optical fiber. Meanwhile, stress is generated in the optical fiber due to forced winding, and the polarization state of laser in the optical fiber and the waveguide transmission characteristic are influenced.
